Sorry I can't tell you what the blade tip speed is but I can tell you that the walker 54'' gear driven deck has a better cut than the belt versions.The only draw back is the gearboxes can bust if you really hit somthing large.Blew on apart when I hit a large stump in long grass.It was my fault though becouse I knew better.I should have took in my belt drive scag first.Some people have flamed that deck becose of the gearboxes,but if do take it easy and don't risk it,then you will do alright!

To convert feet per minute to miles per hour, multiply by .01136. Eric is correct. That comes out to 19,000 X .01136= 215.84 mph. At 18,500 X .01136 we arrive at 210.16 mph. Obviously, there is very little difference in blade tip speed once you approach the legal limit. I have yet to see a <b>new</b> ZTR with blade tip speed listed below 18,000 fpm. I know for sure the older Toros were slower than that, though.

Now a mower with 16,500 fpm blade tip speed would only be traveling 187 mph. There would likely be a noticable difference in quality of cut at high speeds with this slow a blade tip speed.
